It's a commercial west end version. I'd be surprised if it's over 3 hours.
The Lehman Trilogy - 3 hours 20 - yes, it started in the National - but is now in a commercial space.
The Inheritance - both parts run well over 3 hours
In terms of other Cyranos, Robert Lindsay's at the Haymarket was a 3 hour version, the recent National Theatre of Scotland version ran 3 hours 5, Joseph Fiennes for Chichester was 3 hours 10
We don't know much about the script they are planning on using - it is different to the one Lloyd directed on Broadway with Douglas Hodge (which was the Ranjit Bolt) - this one would appear from the picture to be a Martin Crimp version.
Is Crimp known for brevity?
But 3 hours plus seems to be the norm - there are shorter versions - so there might be hope. But I wouldn't expect a 100 minute no interval evening
I saw the Kevin Kline/Jennifer Garner version on Broadway in 2007 and liked it a lot(mostly because of Klines expertise in erm, overegging the pudding and making Cyrano into a tribute to Inspector Clouseau at times): I like James McAvoy a lot as an actor but will wait to see who else is in this before getting too excited about booking to see this.
